Schematic diagram showing AnABlast profiles obtained in a theoretical genomic region with a two-exon gene. The peak-height is the maximum accumulation of protomotifs in a specific genomic position (BLAST alignments including low bit-scores). Peaks with a protomotif accumulation above a peak-height threshold are considered as putative protein-coding regions (coding-signal). Significant peaks matching a known exon represents true positive peaks, while those underlying a genomic region without known exons are considered false positive coding-signals. Well-known exons which do not significantly accumulate protomotifs (peak-height below the threshold) constitute false negatives
